i; and cleaned asa continuous operation while the implement is inmotion, and the cleaned grainiis stored temporarily ina storage tankcarried by the implement andffrom which it is deliveredto wagons orother independent wulreceptaclesfrom time to time as required;

A portion of such a combine is illustrated and described in oura'pplicatioin'Serial N o. 276,-

238, filed May ,9, 1928, of which application this is a division.

The present application is directed to the provision of improved doormeans for effecting or controlling the discharge of the grain from thisgrain storagetank on'the combine,

into a wagonalongsidetlie combine. One

,ig of the features of this door means is the'op'- f ei'ating,arrangement thereof whereby the same ma'y be quickly andfeasily movedbe-y tween open and closed positions and may be made to assume anyintermediate vposition j for graduating the flow ofgrain, and wherebythis door means is prevented from tWisting, binding or jamming under thepressure of the grain.

Another feature of the invention is the proi vision of two or more doorsfor securing a rapid discharge of the grain from different.

parts of the storage tank and for effecting a distributed heaping of thegrain in the Wagon, such doors being operatively connect.-

,- i ed for simultaneous actuation. A Y

Another obj ect of our invention is the prol vision'of pivoted grainchutes leading from thedoors, and cooperating means associated therewithfor preventing bulging of the f; doors under the weight of the grain,and

means for preventing leakage of the grain between the doors and thechutes.

In order to acquaint those skilled inthe art.V` with the constructionand Operation -of Vourv invention, we have shown in the accompany-` ingdrawings a speoic illustrationembodying the preferred form thereof.

The near side of the tank,as viewed inFig-.i

1, is sustained on tubularsupporting bars 42.V

The Astorage tank 26 is shallow at one side and deep at the other side,the bottom plate sloping in the manner shown in'Fig. 2, so that grain,as it comes from the outlet 25 located above the :deep portion, 'fallsinto the z' deep side =of the.tankand by this arrange-y ment it will benoted that nearly the entire porting-bars '42'. l l A journal or bearingmember 43 is posi-- l" tioned on the outer end of the axle 13 and isprovided with an integral'upward'ly extendingr flan-ge .44, .divided atthe upper edge and formed into Va plurality of radially disposed splitsockets 45, which receive the lower ends of the -bars y42 and arer heldin clamping engagement therewith `by rmeans yof bolts 46. Thefbars .42extend radially from the sockets 45 and are provided with caps A7arranged tofengage'on ,the under side'of angle `plate 49, and are,preferably., secured thereto by bolt'fiv50'in thelugs .48, as shown inFig.' 2. The angle plate 49 engages beneath the deep endrf ythe`t.an;l.,as shown, and the downwardly extending edge-5l is riveted toVthel downwardlyextending portion 52 of the tan-k bottomv plate lhilethe supporti-ng means for the deeplsideof the-- tank has :beenillustrated and described, it has not been 35. claimed herein as itformsV the subject matter oft-lie application abovementioned.

`The side plate 33 of .the'tank is cut away adjacent ato the lower edge,providing an opening 53, the edge Aof which is reenforced 3,79 alongthetop by an angle har 54 secured to' the-inner side of the plate v33yby rivets 55.

Verticallyextending angle bars :5.6 are secured tothe side plates v33aof the tank by suitable means, and spaced therefrom yby :re-

' 4 g enfforcing'bars 58f-for providing space for 'the edge 57 of the?door 59 to slide 'between the-bar 56 and the plate/...3.3.` rBhe-re areAtwo vertically sliding doors .each `having'racks 260 on the Youterfaces thereof and 'secured thereto' by 4.53' lugs 16.1 and rivets562,.;and the same are arranged to operate vertically by .means of.pini'ons 63 mounted von and rotatable .by the I shaft mounted in thebearings 65. The

shaftv 64 has .additional 'bearing support and mais held againstmovement in a longitudinalV direction .by :means of' collars 66V securedthereto and rotatable'in bearings :57 in the manner illustrated.; Acrank handle '6'4EL isl dbwnwardly'extendilng flange portion 52 of.

fio-1 thefbott-m plate 35, 4and the ends of 'said ledge plate are-bentupwardly. 'and arerig- 1dly'fsecurecl to the plates"68 i-nia manner toVprevent leakage of grain between the openl ingof 'the door andthepivotally mounted 6:'- j grain chute. A second ledge plate 73,si1fni-lwe ght thereof is carried by the tubular supl Y Y y n y door, but, atthe same time, ypreventmgoutlar to the plate 7 2, is mount-ed above thelatter and spaced therefrom by cylindrical spacing blocks 73a. Theupwardly bent ends 7 4of the plate 73 are secured to the upwardly bentends of the plate 72, thus rigidlypositioning Ythe ledge plate 73 infront of the lower edge of the door 59 and leavingfsuficient clearanceto allow free sliding of the ward bulging of the lower part lof the`door when the tank is filled with grain and the door is. closed. Itwill be noted also that by providing spacingy .members f of cylindricalform between the ledge plates 72 and 7 3, the spacing members will notobstruct passage of `the grain ybetween the two ledge plates,V

so that thezspace for receiving :the :lower edge* o-f the door willvalways, remain clear of the grain, thusfacilitating closingy the door.Positioned at the vlower edge :of eachdoor 5.9 isa grain chute7 5adapted to dischargeA into a `wagonl alongside the combine. Each.' chutecomprises a scoop-like: member of sheet K metal .having a relativelywide, flat fbottom 76 .andv vertical .sides 77, the. reariendsjof whicharesecured tothe :pla-tes r68., by means ofbolts 78, .which` so positionthe fchuteithat the'rear edge 79 of thetbottom portion engages beneaththe lower ledge plate 72, which acts as a stop therefor and yprevents.leakage of grain therebetween. Washers 80 and`8'1 are positioned on thebolts; 7'8 Aforvfsuitably spacing the .chute 75 from 'thespla'tes 68andt for permitting pivotal movement relative thereto.

The outer edge of each-chute .isiprovided with a reenforcing flange 82,which is' 'aris its vinoperative position. The hook 83l is provided witha shank "84, pivotally mounted at 85 for permitting the sametoswi'nginto Vthe position shown in dotted outline lfor holding thechute 75 in itsupwardlyuswung position when not being used.

It will be seen from the above that they two doors are opened andclosedsimultaneously. It l'shouldbenoted lalso that by providing the racksandpin-ions on opposite sides of each `door the doors can rvbe' opened 1and .closed easily and Iquicklywithlittle effort on the part of theoperator, and that a'lsorby lthis construction bindingfof the doors inoperation is prevented,- as both'sidfe edges of the doors are lmoved atthe 'same 'timje.`

spacedapart as shown, so that the-grain will maderapid if desired. j

. Attention is'also called to thedfact that vin combines such as thatillustrated where the'storage tank is carried above t'he-tliresh-` ingand cleaning housing the grain elevator .'Also, it is preferable toprovide two-doors,

24 may be extended up through the bottom of the tank adjacent to thedischargeside thereof, the two doors permitting discharge from oppositesides of this elevator. `Such arrangement of doors also provides pointsof discharge from different parts of the tank of sufficient height toclear the side of a wagon bed without necessitating that the tank beraised considerably above the threshing and cleaning housing.

It will be understood by those skilled in the art that the presentinvention is capable of certain variations and modifications withoutdeparting from the spirit of the invention, and we do not wish to belimited to the exact details herein illustrated and described, butdesire to avail ourselves of such variations and modifications as comewithin the scope of the appended claims.
